Docklight works very well will a large range of USB, PCI or PCMCIA accessories for serial communication, but it is very difficult to specify the individual performance and accuracy. It is influenced by many details of your hardware and software configuration, and especially USB devices introduce unspecified delays and latency times.

Our recommendation is our “Docklight Tap” RS232 data tap for USB. It is especially designed for low latency and high monitoring accuracy, and Docklight has built-in support for fast and direct access to the monitoring data. This allows full duplex RS232 monitoring applications with much higher precision compared to standard USB-to-Serial accessories.
